Abstract

The utility model relates to a drilling machine for directionally drilling hole ends. The upper part of the drilling machine is provided with two motors which respectively forward and reversely rotate to drive a center gear shaft and an external tooth ring. Three planetary gears are arranged between a center gear and the external tooth ring. Under the functions of the center gear and the external tooth ring, the planetary gears spin and revolve. The center gear, the external tooth ring, and the planetary gears form a differential planetary gear strain, and respectively drives a center cutter, an external ring cutter, planetary cutters to drill in broken rocks. The utility model is suitable for the directional drilling of large calibers, and has the advantage of high drilling rate; the drilling machine does not generate torques, and realizes the balance in a drilling torque well. Thus, when directional drilling, direction, granulation and deviation correction are all easy to realize.

Description

A kind of directional drilling hole subdrilling machine
The utility model is applicable to the directional drilling in drilling well, boring field.
At present, be applied at the bottom of the hole of directional drilling power have screw drill (" controlled directional drilling technology ", sky over the river longevity, Zhou Tiefang etc. write the Geology Publishing House, publish in April, 1994, the 243rd page) and the worm gear brill (" directional drilling technological principle ", Wu Guanglin writes, publishing house of Chengdu Univ. of Science ﹠ Technology, published in 1991, the 188th page), these two kinds of power are power source with the flushing liquor, thereby are applicable to small-bore directional drilling ( 300mm is following).They produce countertorque when creeping into, under the effect of countertorque, drilling rod is turned round, and make that the orientation of deflecting direction when static when creeping into is inconsistent, make detorsion angle of drilling rod generation.Therefore in real work, the detorsion angle must be eliminated, otherwise oriented deflecting tool established angle value will be changed, and actual orientation and design orientation are not inconsistent.The detorsion angle is relevant with many factors, determines more complicated; In addition, drilling rod is subjected to the influence of moment of torsion to be easier to fracture, thereby the Material Strength of drilling rod is required also than higher.
In view of the deficiency that prior art exists, the purpose of this utility model is a kind of novel rig of design, and it can carry out the heavy caliber directional drilling, solves the problem that drilling rod is turned round, the instrument established angle is difficult to determine in original directional drilling technology simultaneously.
Task of the present utility model realizes as follows: a kind of directional drilling hole subdrilling machine, its top is made up of motor A, motor B, reduction box, two motor forward and reverse rotations respectively, motor A passes to sun gear shaft by a pair of gears engaged in the reduction box with power, and motor B passes to external toothing with power by a hollow transmission cover to gears engaged by in the reduction box another; Being with central gear outside the middle part of sun gear shaft, is 3 planetary gears between central gear and external toothing, and sun gear shaft drives central cutter, and external toothing drives the outer ring cutter, and planetary gear drives the planet cutter by cutterhead.
The utlity model has heavy caliber directional drilling, the broken rock of section, the characteristics that drilling speed is high entirely of being suitable for, simultaneously because suffered reaction torque equal and opposite in direction, the direction of two motors is opposite, make rig top equalising torque, transfixion, thereby connection drilling rod thereafter, do not produce and reverse, during directional drilling, orientation, deflecting, correction are all determined easily, can be satisfied the needs that differently creep into engineering down.
Description of drawings:
Fig. 1 is a structure diagram of the present utility model.
The utility model will be further described below in conjunction with accompanying drawing.
Two motors are arranged at the utility model top, be respectively motor A1 and motor B11, two motor with positive and negative rotations, motor A1 passes to sun gear shaft 12 by a pair of gears engaged in the reduction box 2 with power, motor B11 then passes to external toothing 9 with power by hollow transmission cover 10 to gears engaged by in the reduction box 2 another, thereby sun gear shaft 12 is rotated in the forward external toothing 9 reverse rotations.Being with central gear 4 outside the middle part of sun gear shaft 12, is three planetary gears 8 between central gear 4 and external toothing 9, planetary gear 8 rotation and revolution under the effect of central gear 4 and external toothing 9.Central gear 4, external toothing 9 and planetary gear 8 have constituted differential planetary gear train, and three Fen Do drives central cutter 5, outer ring cutter 3, cutterhead 7 and planet cutter 6 and creeps into fractured rock.The broken most of work plane of planet cutter, the broken center of central cutter rock, the outer ring cutter finishing borehole wall.Under certain parameter cooperates, two reaction torque equal and opposite in directions that motor is suffered, direction is opposite, thereby does not produce and reverse, and has realized creeping into moment well inner equilibrium, has improved the condition of directional drilling, has reduced the material requirement to drilling rod.
